There are around 40 flights a day to Doha from the UAE, and the sudden halt on Qatar air travel is the latest blow to carriers in the region.

Emirates, Qatar Airways and Etihad were among 10 airlines on which the Trump administration imposed tough new restrictions in March. The carriers are now required to prevent passengers flying from their Middle East hubs to the United States from carrying almost all types of electronic devices in the cabin.

Monday's crackdown on flights is part of a broader set of restrictions on travel involving Qatar and its citizens.

The UAE government gave Qatari diplomats 48 hours and Qatari residents and visitors 14 days to leave the UAE "for precautionary security reasons." UAE citizens are also banned from traveling or transiting through Qatar.

Saudi Arabia's civil aviation authority said any carrier from a third country wishing to fly over the kingdom to Qatar would need to apply within a week for special permission.
